The alloy will harden by cold working or by heat treatment astj see “Heat Treatment” and “Tempering”. Although no invariable rule prevails between the terms blooms and billets, and they are frequently used interchangeably, the following size distinctions are in general use.
Historical Version s – view previous versions of standard. The alloy can be fusion or resistance welded.
This specification covers cast carbon and alloy steel ingots and strand castings, semi-wrought ingots and atm castings, and rolled or forged blooms, billets, and slabs for steel forging stock. It is known for its toughness and capability of developing high strength in the heat treated condition while retaining good fatigue strength. AISI is considered to be a “through hardening” steel such that large section sizes can still be heat treated to high strength.
The alloy may be cold worked, in the annealed condition, by conventional methods and tooling. For high strength over ksi the alloy should first be normalized at F prior to heat treatment. Consult the alloy supplier in regard to hot working. Bend radii should be 3t or greater.

It can be bent or formed by spinning or pressing in the annealed state.

The temperature for tempering depends upon the strength level desired. See “Tempering” for strength levels.

This abstract is a brief summary of the referenced standard. Materials shall be manufactured and furnished in a condition that can withstand, for an indefinite time, exposure to all climatic conditions without developing any external or internal cracks. There were no books found for the applied search filters. It has good ductility.
